A usb phone adapter is a device that allows for the direct connection of your phone to the computer so that you may access Skype and other online calls on the regular home telephone. The regular functions of the phone remain the same via the landlines, even if you install the USB phone adapter. A manual or automatic switch is possible for accessing the Internet calling mode, which serves for dialing purposes as well. The phone usage will thus remain the same, no matter whether you receive Internet or land calls.
How does the USB phone adapter function? Without any further equipment, the adapter ads a new mode to the phone. The adapter can be used on any kind of phone model, and the ringing remains the same for landlines and the Internet. The power for the USB device is taken from the computer, and whether regular or cordless, the phone operation remains unchanged.
There are devices that enable auto-switching for incoming Internet calls or landline calls. The only way to make a difference between the calls is by following the LEDs that go on: there will be one for power, one for the Internet and one for landline calls. The application is possible thanks to special softwares that are installed on the USB phone adapter. Although almost anyone can use the device, there are some technical requirements to be met nevertheless. Do not order a product over the Internet unless you are sure to meet the following technical conditions.
